[SOLVED] New graphics card doesn't work.

[linus.johansson020]

Hello, i just ordered a new Graphics card, RTX 3070(ASUS OC). I plugged it in to my new computer and it worked fine. When i installed the drivers and restarded the computer it wouldn't boot. I then plugged in my old graphics card again and everything worked perfectly fine. So my computer works with my old AMD Card but not my new RTX 3070. I have new PSU to support this card so the PSU should not be the problem. With the 3070 i dont get a signal neither do my keyboard and mouse light up. When the 3070 is plugged in the VGA Led lights up red. Althought everything inside the computer lights up normally and the fans spin. The leds on the 3070 light up as normal.

Things i have tried:

Clean install on new drivers and also removed the old AMD drivers.

Changed PSU cables.

Testet all PCIe slots on my motherboard.

Reseted CMOS.

Specs:

Cpu: i7-6700k

Motherboard: z170-a ASUS

AMD Card: Radeon rx480

NVIDIA Card: ASUS RTX 3070 8GB OC

PSU: Corsair RM750.

RAM: 16gb corsair vengeance.

Thanks in advance!

Use DDU,after you are done with wipping the drivers,swap the cards and boot into safe mode.
Try that.
